Ownership of website backups

I activated website backup module and after first backup I found out that I can't get access to backups through "backup" symlink in FTP connection. It was because owner of this folder is root. I also checked part of code in /usr/local/ispconfig/server/cron_daily.php responsible for it.

In this way user can download through FTP zip with backup of his website. If not why does script create symlink in website folder?

Moreover I want ask if it's possible to change type of backup frequency in next version of ISPConfig? I think the better way is to use separately:
- number of backups in day AND week AND month ("and" not "or")
- number of backups to carry in backup folder

For example in AutoMySQLBackup script it's possible to create 2 backups per day and carry last 5 of this type in daily folder. Moreover 3 backups per week and carry last 10 in weekly folder. And finally 1 backup per month and carry last 6 in monthly folder. I know it's stupid example but I want only show you how flexible is this type of frequency. It's not so hard to implement but it require additional field.
